Secure Social Network Based Healthcare

Healthcare system holds a huge amount of data due to the number of tests taken by the patients and are maintained in physical files or digital files in form of records. At the end of the treatment, a discharge summary of the files will be sent along with the patients. All the records of the patients are maintained in the hospital by MRD (Medico Record Department). Maintanence of records are of very high cost and data security, integrity should be maintained. When patients migrate from one hospital to another, they ought to provide their past records to the doctor for diagnosis. There is a very high probability for the patients to miss their records after many years. A social network based system can be developed in which the patient’s data is stored in cloud and can be shared among the healthcare centres. Each hospital can send requests regarding a patients’s past records to other hospital and records can be retrieved. This helps doctors to have a greater incite on the reports, and repeated tests are avoided for the search of the missing information. As medical records are very sensitive, security and privacy concerns are high. To secure data, blockchain is used in which the data are stored in off-chain and their hashes are stored on-chain. The data in off-chain are encrypted using Advanced Encryption Standard(AES).
